High-Quality Material: Made of high-carbon steel with centerless grinding. These drill bits offer high precision, impact resistance, and good toughness.
Fine Cutting: This product features arc cutting, which reduces cutting resistance and effectively improves drilling speed. The perforations are neat and smooth with no broken edges, allowing for fine and smooth circular surfaces to be cut.
[High-Speed Chip Discharge] This product adopts a beveled cutting edge design. Sufficient chip discharge outlets are ensured to facilitate chip removal. This effectively improves work efficiency.
[Precise and Stable] The middle teeth of the drill ensure precise and stable positioning during operation, effectively preventing wobbling and slippage. The X-shaped bit provides visibility and stability during operation. This allows for ideal circles and accurate holes to be created.
